What Causes Watery Eyes Or Dry Eyes?
Watery eyes or dry eyes can have various causes, ranging in severity from 'worrying' to 'needs attention'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose watery eyes or dry eyes, we could:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.
Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "watery eyes or dry eyes" as a symptom. Here are eight of many possibilities:
- Iritis
- Sjogren's Syndrome
- Rheumatoid Arthritis
- Dehydration
- Juvenile Rheumatoid Arthritis
- Sarcoidosis
- Dry Eye
- Low Estrogens
Step 2: Build a Symptom Checklist
We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:

having hot flashes

rheumatoid arthritis

frequent painful inguinal nodes

long term neck pain

vision disturbances

moderate eye discharge

high alcohol consumption

being easily irritated

dark urine color

hot flashes between period

severe tongue swelling

very bloodshot eyes
... and more than 90 others
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of watery eyes or dry eyes:

Based on your response to this question, which may indicate very dry eyes, dry eyes, watery eyes or very watery eyes,
The Analyst™ will consider possibilities such as:
Dehydration
The body's response to dehydration is to conserve as much fluid as possible, including fluid in the eyes, which can lead to dry eyes.
Rheumatoid Arthritis
